Rectangular solids and cylinders are somewhat similar because they both have two bases and a height. The formula for the volume of a rectangular solid, [latex]V=Bh[/latex] , can also be used to find the volume of a cylinder. For the rectangular solid, the area of the base, [latex]B[/latex] , is the area of the rectangular base, length × width.
1. Find the volume of the solid of revolution generated when the area described is rotated about the x-axis. (a) The area between the curve y = x and the ordinates x = 0 and x = 4. (b) The area between the curve y = x3/2 and the ordinates x = 1 and x = 3. (c) The area between the curve x2 +y2 = 16 and the ordinates x = −1 and x = 1.
Area = W × L = 2 inch × 3 inch = 6 inch 2 To calculate the numbers (2 × 3 = 6) is the easy part. As for the unit, since we are multiplying two lengths with the unit inches together, logically, we can write the resulting unit as inch 2 (square inches). The 2 on the unit represents area.
To understand that in order to find volume and surface area of irregular solids, we must find the basic solids (prisms, cones, pyramids, etc.) that make it up, and calculate from there. This video goes over the confusing concept of finding the volume of irregular solids.

Lesson 13-4 Congruent or Similar SolidsIf the corresponding angles and sides of two solids are congruent, then the solids are congruent. Also, the corresponding faces are congruent and their surface areas and volumes are equal. Solids that have the same shape but are different sizes are similar. You can determine whether two solids are similar ...
Daily Work: Students will break down the vocabulary found in Lesson 1 of Unit 3. Also will be able to explain the surface area-to-volume of an object and how it relates to cells. Can you calculate? We will see tomorrow! 10-30-19 Ice Breaker: Students will calculate the surface area-to-volume...practice the skill you have learned.
Surface Area of Prisms Surface area is a two-dimensional property of a three-dimensional figure. Prisms have two congruent, parallel bases separated by lateral faces. Lateral faces are congruent rectangles with a height equal to the prism, unless oblique, and bases equal to the side lengths of the...
